TVs that do anything more than displaying a signal exactly as it’s input shouldn’t exist.

Some of that input could do with a bit of tweaking though.

I wouldn’t mind if the TV was able to do things with the audio track, like remove background music, or lift the volume of people speaking, or erase laugh tracks/live audience hooting& hollering.

There’s probably similar manipulation that you could do on the video side (eventually, once TVs stop getting the worst processors ever, not here and now). Imagine a prompt that says “Airbrush every recognisable brand name on-screen so that it blends with the background”.

I seriously doubt if any major manufacturer would do that kind of thing though, so better get working on jailbreaking those TVs.
